The big improvement here is the new night mode. Now, the app can switch to a darker color scheme when you're reading at night so you're not blinded by the white screen. You can activate this mode by flicking down with two fingers anywhere, in the settings menu, or let Tweetbot do it automatically based on the brightness. Tweetbot also gets some account improvements. You can now instantly access accounts by swiping across the avatar at the top or reorder the accounts you have by just dragging and dropping them.
